2. Inaccurate alignment
We rarely discuss the impact of misaligned belt guides when talking about timing belt life, but this factor is important. When working, each timing belt moves around its track at a speed of thousands of revolutions per minute. The huge friction generated by the opening and closing movement of this face-to-face contact will cause the belt to be damaged in advance. Therefore, before and after installing the timing belt, we must carefully check the installation positions of the various components of the timing system to see if they are aligned accurately, so that we can try to avoid damage to the timing belt due to inaccurate installation positions. damage.
3. External contamination or damage
Anything that comes into contact with the timing belt can damage the timing belt, which is why the whole system is covered while the timing belt is working. However, even if most of the timing belt is protected, there will still be a small amount of oil in the engine, such as engine oil, coolant, etc., which will affect the timing belt, causing it to slip or chemically corrode. Also, small stones, small metal shavings, or other debris can find their way into the timing belt area, which can also damage the belt.
4. Incorrect installation
This is the part we can control most successfully, as long as we strictly follow the instructions for use. The instruction manual comes with the replacement timing belt. The contents of these instructions are the result of practical research and testing. Do not use a lever or screwdriver to forcibly pry the timing belt to stretch it into the normal track, because the timing belt is not designed to stretch. When installing, the tension on the timing belt should be released, put the timing belt on the track first, and then restore the tension. Use special positioning and tensioning tools for installation, so that you can ensure that the timing belt is installed, positioned and tensioned correctly, and that all parts can rotate smoothly.
